I got the inspiration from a treasure box. I was impressed by the way of thinking of the ancestors who regarded tea as a treasure and that motivated me to create this design. I expressed the decoration reminiscent of a jewelry box by putting the brim on the top and bottom of the body. The piping on clothes and cakes also inspired me to design it. It is a form that people can hook the brim with their fingers that and comes from the motion of picking up a bowl as previously explained.
